Super Mario 64

I think it is much harder to go back to Super Mario 64 than it is to go back to Super Mario World. 2D platformers have only come so much further. If someone likes Ori, they most likely will also enjoy Super Mario World. 3D games, on the other hand, are miles away from where Super Mario 64 is. That isn't to say Super Mario 64 is bad- it is gosh darn excellent! But it is a weird game to go back to. You can control the camera (originally with the C buttons, now with the control stick), but only in increments. Mario has a wide range of options to platform (a timed triple jump, a wall jump, a dive, a long jump, a backwards somersault), but the character has a slushy response that lacks the control we're used to with modern Mario. And I will say I still basically find it charming, but so many areas just exist in a sky box.
I don't know if that little bit of charm comes across to first time players, but I do think the overall charm comes across. There is such tight level design that is largely lacking in modern games- even modern Mario games. Perhaps this design ethos was eschewed* because bigger often reads better to the unobservant, but maybe also because the tight simple level design can be exploited. In Cool, Cool Mountain, you can jump off the downhill track against the big penguin and cut far ahead. In Whomp's Fortress, you can backwards somersault to skip overcoming bottomless pits and Thwomps. Heck, In Bob-omb Battlefield, you can skip a large section by just running up a steephill. The thing is- all of these are PLEASURES NOT PROBLEMS. Remember all the times in Breath of the Wild when you used some insane creative way to solve a puzzle? You flipped you controller over to solve that one marble madness shrine or whatever? It felt great, and it still feels great to overcome puzzle after puzzle that way in Mario 64. Creative problem solving is fun. Speed running is fun. I'd take Whomp's Fortress over a big desert any day.
My last thought on SM64 (for now), the progression is great. You get in the castle and there is really only one place to go. Once you beat there, the game tells you you have enough stars to check out other areas, but specifically recommends Peach's observatory** where you will find a secret slide level. Now you know this game has secrets. Then you will check out the other room, you can go to with your available stars because the game has told you there were more rooms available. Now you've opened up two more rooms which you have been encouraged to explore. Not only do you get a fair amount of gameplay styles within these rooms, but you also get to check out areas that are wildly varying. The only thing that binds these levels is their verticality which is an exciting and new element to these 3D games. Even if you find the secret stars within this first area (of which based on my memory there are two more), you still must play one of these areas a second time before facing Bowser. This teaches you that replaying levels and receiving new missions is a core element to this game.
It is so well crafted that I found myself struggling to put it down. 24 years later and Mario 64 still floods my brain with dopamine.
